You can choose either portrait (vertical) or landscape (horizontal) orientation for all or part of your document. When you change the orientation, the galleries of predesigned page and cover page options also change to offer pages that have the orientation that you choose.
Note If you select some but not all of the text on a page to change to portrait or landscape orientation, Word places the selected text on its own page, and the surrounding text on separate pages.
Note Word automatically inserts section breaks before and after the text that has the new page orientation. If your document is already divided into sections, you can click in a section (or select multiple sections), and then change the orientation for only the sections that you select.
